The compression hardness Y of the memory sponge at 30% is 1.65-1.95KPa, and the compression hardness Y and the density rho meet the following conditions: y · ρ is 71 or more and 89 or less.
In order to fix the waist of the infant, the restraining belt has elasticity. The binding belt is a flat elastic belt. The force L required for 100% stretch of the elastic band is 100-300N.
In order to simultaneously support and protect the head and the waist of an infant safely and comfortably, the density ρ of the memory sponge, the compression hardness Y of 30% and the force L required for 100% stretching of the elastic band satisfy the following relationship:
L=ρ·Y2+δ;
wherein, delta is an adjusting factor of the required force when the elastic belt stretches 100 percent, and the value is 90-110N; the above formula only performs numerical calculation, and does not perform unit operation.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
